The prosecutor of the International Criminal Court is warning Israel that if it doesn't provide reliable information for her preliminary probe into possible war crimes in Palestinian territories she may be forced to decide whether to launch a full-scale investigation based only on Palestinian allegations.

Fatou Bensouda said in an interview Tuesday with The Associated Press that she hasn't received any information yet from either side regarding last summer's Gaza war. She stressed that it was in "the best interest" of both sides to provide information.

Bensouda opened a preliminary examination in mid-January after the Palestinians accepted the court's jurisdiction dating back to just before last year's Gaza war in which more than 2,200 Palestinians, including hundreds of civilians, were killed. In Israel, 67 soldiers and six civilians were killed.
